一種改善圓陣波束指向性性能的加權(quán)方法
A WEIGHTING METHOD FOR IMPROVING BEAM DIRECTIVITY OF THE CIRCULAR ARRAY
-
摘要: 該文在分析圓陣波束指向性的基礎(chǔ)上，提出了一種改善圓陣波束指向性性能的對稱指數(shù)加權(quán)方法，利用該方法能較有效地抑制旁瓣，而主瓣的增寬效應(yīng)并不明顯。

Abstract: Based on the analysis of the directivity of the circular array,a symmetrical exponential weighting method which improves the directivity of the circular array is developed in this paper.Using this method,the sidelobe level can be efficiently rejected and the mainlobe width be little widened. -
